Compliance is the proportion of times the two MPs in a pair vote the same way in a given session. Similarity is the average vote similarity between the two MPs in a pair. Neighbor is a dummy variable equal to one if the MPs in the pair are randomly assigned to sit next to each other during that session. Same Party is equal to one if both MPs in the pair are in the same party for that session. Dyadic-robust standard errors are in parentheses and dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Sharpened q-values (Anderson 2008) for non-placebo tests are in <>. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. Strata FE are dummy variables for whether both MPs in a pair were pre-assigned seats, one MP in a pair was pre-assigned a seat, or neither MP in a pair was pre-assigned a seat. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
